ABB Turbo Systems Ltd. recent- ly announced plans to expand the
RR..1 turbocharger product family with the introduction in spring 1991 of the RR 131, the smallest frame- size BBC Turbocharger. The com- pany already markets the RR 151,
RR 181, and RR 221.
The RR 131 is designed for en- gines with output ranges as small as 290 to 760 kW per turbocharger.
With the new unit, ABB said typical high speed diesel engines will run with up to 20 bar brake mean effec- tive pressure at outstanding brake specific fuel consumptions as well as moderate exhaust gas tempera- tures.
During the first trials of the RR 131 on the test bed, ABB engineers measured an overall turbocharger efficiency of 60 percent at compres- sor pressure ratios between 1.8 and 2.6.
According to ABB, the RR 131 will handle air volume flows be- tween 0.45 and 1.30 m3/sec. at a 3:1 compressor pressure ratio. The overall turbocharger efficiency level will be around 60 percent while compressor pressure ratios will be about 3.2 for large trims and 3.7 for small trims. Turbine inlet tempera-
